A family pays $6.00 to park at a baseball game. Tickets for the concert cost $7.50 per person. The family spent a total of $43.50 for parking fees and tickets to the baseball game. The situation can be modeled by the equation 43.50 = 7.50n + 6, where n represents the number of tickets purchased. How many tickets did the family purchase?

what grade level is this? need to know so i can look in my old textbooks!

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
